  • Retries are normal. Webhook delivery is at-least-once. Design consumers to tolerate duplicates and out-of-order arrivals where possible.
  • Asynchronous by design. Payers, chains, and your servers operate on different clocks. UI and finance should not assume synchronous finality.
  • Eventual consistency. API reads, webhooks, and portal views may briefly diverge during transitions. Reconciliation jobs exist to converge truth.
